Geospatial Data

We're providing geospatial data free of charge in both KML and KMZ format. Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization, and KMZ is a compressed version the KML. BART is providing data to the general public under a simple License Agreement: you never need to register and we don't make you jump through hoops to access BART open data.

Don't use the BART logoOnly we get to use official BART trademarks and copyrighted works to let customers know they're getting info directly from BART versus one of the tons of other places that use BART open data.

Why are you doing this?We want to foster innovative applications, reach a broader audience and encourage more people to choose BART.

Will you help me troubleshoot?If we help you, it's only fair that we help everyone else, too. We simply don't have the resources for that. Let us know about any issues or enhancements you'd like to see, but unfortunately we aren't able to provide technical support for your development efforts.
